In patients with Nazolakrimal Channel (NLK) blockage and operated by external dakriyosistorinostomy (DSR) method, the aim is to study the relationship between lakrimal bone thickness (LKK) and blood serum calcium levels. Tools and Methods: The file of 45 patients undergoing external DSR surgery with the cause of NLK obstruction was reviewed backward. During the surgery, a bone window was created by removing the lacrimal bone piece with the help of a micro-motor. The anatomically vertical and horizontal dimensions of the bone and the thickness of the upper, middle and lower parts under the microscope were measured with the help of the pergel and the relationship of these values with the serum calcium levels in the blood was studied. The average age of patients (n=45) was 54,07±11,67 and the age range was 27-77. The gender distribution of the patients was male (n=8) 17.80% and female (n=37) 82.20%, respectively. The files of patients who underwent external DCR surgery due to NLC obstruction were reviewed. The mean area of the removed nasolacrimal bones was 54.17±17.74 mm2. The mean LCC was found to be 1.45±0.60 mm, 2.13±0.86 mm and 2.50±0.81 mm in the upper, middle and lower thirds, respectively. The mean blood serum calcium level was 9.35±0.36 mg/dl. Conclusion: There was no statistical difference between men and women in terms of LCC measurements. (p>0.05) In addition, no correlation was found between LCC and blood serum calcium levels. (p>0.05) No significant difference was found in terms of blood serum calcium levels in women and men. (p>0.05)
